When I highlight a word(s) on a webpage and right-click on it, I get the option to "Search Google for" the highlighted word(s). I love that feature and use it very frequently. I would like to add "Search Wikipedia for" and "Search Google Images for" as well, but I have not figured out how to do so. I realize that others may wish to add other or additional searches in the same manner, such as "Search IMDB for" or "Search Allmusic for." I have already searched through about:config and through my Windows10 Registry, but I have found nothing. Please inform me as to how this may be accomplished.
